Long time lurker, first time writer. I'd really appreciate some feedback on a) whether this idea is viable and b) if it is viable, how I can start fleshing it out/building a narrative around it. I apologize if my wording is unclear.

It's a pink limousine, of a recent make and model. If a driver is actively operating the limo and there's at least one individual in the passenger compartment, while the limo is running, the driver will become aware of information regarding the current passenger(s). Any information that's been recorded in a visual transcript (either written or pictographic) is fair game; it can be a tangible or digital record, it doesn't matter how public or secret it is, and the driver will perceive it as fact regardless of whether it is objectively true. The driver will take offense to the information they've just learned about the passengers, often to an irrational extent, and become increasingly hostile towards the passengers (beginning with verbal harassment and escalating to physical violence upon prolonged exposure).

My initial impression is that this is three anomaly-archetypes combined: Strange visual image (pink limousine), brain-hack (knowledge on the passenger), and compulsion (irrational hostility). It may be unfair to break down an SCP idea (or story plot) in this way, but it's inevitable when these conceptual components seem disconnected; it feels like three separate effects have been smushed together. The reader asks: Why is the limo pink? Why does the pink limo grant a degree of omniscience? Why does this omniscience (or the pink limo) make the driver hostile? And the reader, in all likelihood, will want answers, or a compelling reason to forget those questions.

I advise revisiting this idea with an eye for connection or explanation. If you do keep all of these elements, then you should have answers to the questions above. If you add or subtract ideas, what you have left should still have some cohesion or narrative purpose, like a theme or a backstory. You can have a scip that combines different anomalous effects, but you should strive to make that scip greater than the sum of its parts. Otherwise, you end up with an anomalous item, not an SCP.

TL;DR: In my opinion, your pink limo that makes the driver all-knowing and angry needs to help the reader know (or forget) why the pink limo makes the driver all-knowing and angry.

Thank you so much for your critique! Looking back at the idea, I completely agree with you - it does kinda seem like a hodgepodge of anomalous stuff with no real connecting thread.

Of the three main components you mentioned, I feel like the "brain-hack", as you put it, is the most important piece, and the other two pieces can be abridged or cut. If I go through with this idea, I'll probably specify that the knowledge the driver gains about the passenger is specifically knowledge that the driver would take offense to, based on the driver's life history and emotional priorities. That way I can cut the cliche compulsion effect - the driver has free will in how they react, it's just that the information they're receiving is hand-picked to be something that would ordinarily piss them off.

As for the pinkness of the limo, I can probably cut that entirely. It's just a picture I had in my head and it doesn't really add anything concrete to the idea other than "more weird stuff = more anomalous".

The main narrative portion of this will most likely lie in its initial discovery? I'm thinking a transcript of a video log (as, from the passenger's PoV, the driver's reaction to learning this information is EXACTLY the kind of thing people film and post online on places like r/publicfreakout), maybe an interview with the driver after he learns some shady stuff about a high-society passenger and decides to enact his own personal justice or something, et cetera. I still need to do some heavy brainstorming, though.

Would this improve the idea, or are there other major problems I need to address? Thank you again for your help - I feel more confident now than I did before :)
